Superior Court Judge Marsha N. Revel's sentencing order, released Wednesday, specifies the actress will be randomly tested for drugs and alcohol until August 2011, when her probation term is over. It's unclear, however, if she'll be required to wear a SCRAM bracelet upon release.

"Lindsay got the typical sentence for anyone who has a serious problem with drugs and alcohol," says veteran criminal defense attorney Harland Braun, who's not involved with the case. "Lohan repeatedly tested the patience of the judge, who saw through all her excuses. That's what addicts do: Tell lies."

Lohan has been allowed to take five prescription medications while on probation: Nexium (for heartburn), Zoloft and Trazadone (both antidepressants), Adderall (for ADD), and the painkiller Dilaidid "sometimes ... for dental pain."

"She has been on the same prescription medication for as long as she can remember," according to her probation report, released Wednesday by the Los Angeles court system. "She has provided medical proof for her prescription drugs."

The report states that in previous drug tests, she twice tested positive for amphetamines and opiates, but those were the result of Adderall and Dilaudid.

Her Full Sentence?

The judge's orders specify Lohan serve her time in the Los Angeles County Jail, which all but guarantees she'll be headed to the Century Regional Detention Facility in Lynwood, Calif., the only jail for women in L.A.

She'll likely not serve her full three-month term because she'll be eligible for early release for good behavior and for the L.A. sheriff's long-standing policy of releasing non-violent offenders early. However, if Lohan is a problem inmate, that could extend her sentence as well, experts say.

A spokesman for the sheriff's department couldn't comment on how much time Lohan will likely serve, stating that her case will have to be reviewed.

An Early Release?

Reached for comment on the possibility of early release, Deputy District Attorney Danette Meyers, who prosecuted the case, told PEOPLE: "I'm always disappointed when inmates are released early."

"People should serve out the sentences they're given, but the jails are not my jurisdiction," says Meyers. "If Sheriff Lee Baca orders her released early due to overcrowding, that'll be beyond my control and the control of the judge. The jails are the sheriff's jurisdiction."

One positive note: Lohan will have a job waiting for her when she's out of custody. Producers for Inferno, the Linda Lovelace biopic, say they won't make the film without Lohan playing the lead role.
